These games can be great to finish off at the end of the day. They can usually be played on an IWB or Smartboard.
- Whomp - like the traditional Boggle but with fun characters to challenge, and with degrees of difficulty suitable for primary school. Seems to only work on Internet Explorer which is a shame. Just search Google for "whomp felids"
- Wordtwist - lots of options including 4x4 boards and 5x5 boards, but much more challenging. Good for older students, and lots of fun to see all the words you didn't get when the game finishes.
- Boggle style games at mochigames.com. Word Spasm is good fun.
